Auto electrician needed for XC90 - South Manchester

[John Brennand]

XC90 T SE AWD SEMI AUTO 2521cc, petrol.

Interior heater blower motor making a racket - so took it it in to my local garage. They got the old motor out quite easily and on testing it was a faulty bearing and was seized.. They ordered and fitted the correct new part but it wasnt working. They tested the resistor and they said it had an electrical fault. They got a new resistor and bypassed the old resistor - but still not working. So they believe it is an electrical fault somewhere and beyond their expertise and have recommended me to take it to an Auto-electrician.

What I am thinking is to take it in to get diagnosed on VIDA first and take it from there. There are a couple of Volvo garages close by - one independent (Hallmark) one MD (Rybrook) that would do that.

Is anyone on here able to help or recommend anyone else with "electrical" expertise ?

Any other suggestions/options/thought are welcome - particularly on what usual suspects might be at fault.

Thanks for any input. John

Forgive me, but as you describe it, it sounds as if they have no idea what they are doing.

"bypass the resistor" - what does that mean? And why would that be necessary? It's a simple replacement of old for new, *if* that is indeed required. From what you describe the blower was noisy but hence running when you took it in and if that was the case, there's nothing wrong with the "resistor" (it's actually a FET-based regulator).

Sounds like they've buggered something up, possibly using the wrong part(s). I'd take it to an independent at this point.

VIDA is unlikely to provide any diagnostic insight in this area but it's a simple setup and a decent garage should be ok with it.

Thanks... I was suspicious when the job went to the mechanic I have never dealt with before ! I just called Hallmark in Stockport and they said exactly the same as you !

I am taking it in on Tuesday and they will sort it out

Lesson learned !

Cheers John

All the best with it. Unless they've done something monumentally silly it should be easy enough for a competent garage to straighten out.

hallmark will soon have you back on the road top guys and efficient service iv used them before.

And they did..!

As suspected on here - it was a blown resistor - first garage obviously hadnt tested it correctly.

Thanks for all the input.
